I haven't had a scenario were passing multiple VF NICs to the guest was necessary. In theory it might happen there as well, if you have multiple NICs (with persistent and random MACs) in the guest. But usually you just have a single VF inside the guest and then you're fine. The scenario that I'm targeting is on the host side mostly.
